I've been working on this theory every waking moment for the last couple of months:
I think that Oda is seriously a furry, here is all the evidence:
1. Zoans are obviously his way to let his inner animal out through his art
2. Chopper should theoretically be able to turn completely human because he is a human zoan, but since oda is a furry he never does
3. even when they're not zoans, people's names, attacks, and themes usually have something to do with animals. For example, most of zoro's attacks have some animal pose, hinting that zoro is a furry too.
4. there are furries everywhere when there isn't a cover arc going on.
